加氢预精制反应器是加氢装置的核心设备,操作工况要求十分苛刻,因此对加氢预精制反应器的结构设计、制造与检验提出了严格的要求。利用ANSYS的有限元参数化建模以及优化模块对某一煤制油厂的加氢预精制反应器封头与筒体连接区进行优化设计,使连接区的应力水平达到最低,材料最好、结构最优化。 Hydrogenation pre-refining reactor is the core equipment hydrogenation unit, the operating conditions are very demanding, so hydrogen pre-refining reactor structure design, manufacture and testing made stringent requirements. The ANSYS finite element parametric modeling and optimization module is used to optimize the connection area between the head and the cylinder of hydrogenation and prefining reactor of a coal-based oil refinery so as to minimize the stress level in the connection area and to obtain the best materials. Structural optimization.
